HST was transported into orbit aboard Space Shuttle Discovery (mission STS-31) in April 1990. It was scheduled to be orbited earlier, but the shutdown of the Shuttle program following the Challenger accident delayed its deployment, not to mention increasing its maintenance cost because it sat on the...

Yes, the predominant units are all still metric, althoughcosmologists exploring the earliest instants after the big bangoften use units of planck time instead, but this of course is stillbased on the metric system. .
+++ .
The only other two units of time relevant in Astronomy andGeology are the...

The ChallengerExplosion was caused by an external tank explosion. The spaceshuttle broke apart due to gasses mixing in the external fuel tank.The shuttle exploded and the space shuttle was torn apart..

Yes. Mass and weight are different quantities. The mass of the astronaut is always the same everywhere. The weight of the astronaut is the force on it due to gravity, which depends on the mass and the strength of gravity at the point on the planet, moon or space station the astronaut is standing...

If you're talking about who was the first nation to ever successfully place an object in space, the Soviet Union was the first to send a satellite into orbit. The United States was the first nation to successfully place a human being on the moon.

The Astronaut Class of 1978, otherwise known as the "Thirty-FiveNew Guys," was NASA's first new group of astronauts since 1969.This class was notable for many reasons, including having the firstAfrican-American and first Asian-American astronauts. DuringWomen's History Month in March, NASA...

Electrical fault on an O2 canister caused an explosion in the oxygen tank which also damaged the second tank. This left the spacecraft virtually crippled, as the oxygen tanks were necessary for the supply of electrical power. .
CO2 scrubbers became saturated by change in mission profile. The Lunar...

The Hubble Space Telescope is designed to see deep into space. Soit has taken many fascinating photos of the outer reaches of theuniverse, or in our own galaxy. It has accomplished taking manyphotos for scientists to study, and for us to see.

The HST First Servicing Mission occurred over a 10 day period on board Space Shuttle Endeavour (STS-61) in December, 1993 - all of us on the HST program held our breath as the Astronauts installed COSTAR, the corrective optical unit that compensated for the minor defect in the primary mirror (4...

The International Space Station is a large spacecraft in orbitaround Earth. It serves as a home where crews of astronauts andcosmonauts live. The space station is also a unique sciencelaboratory. Several nations worked together to build and use thespace station. The space station is made of parts...

a telescopes vision can be blocked by and astroid or by the clouds.you won't get a clear view when all the dust blocks a lot since itis zooming a lot. the advantages are its also like a periscope witha mirror which give you a clear view of things.

to take photographs of very distant galaxies, and show data of themto NASA. It is used, because there is too much light pollution in alot of places on Earth, making it hard to use a telescope, but inspace there is no light pollution (therefore, it can see thegalaxies that we can't see on Earth).

The first moon landing by Apollo 11 was on July 20, 1969. The final moon landing by Apollo 17 was on December 11, 1972. The Apollo 17 Lunar Module departed the Moon on December 15, 1972, and no human has set foot on the Moon since.

they eat stuff like ice-cream sandwiches and peanut butter sticks. they have to keep the food in plastic bags and they have to suck all the air out to keep it from going mould and so it stays freash for longer

It is very hard you have to train these this things listed belowfor years: How to float in the spacesuit How to contact the team in earth from space How to control the heaviness and weight of the suit How to control the rocket and know what to do if something badhappens Getting used to space food...

There are two different ways to answer this, so I'll give youboth: .
a) The first male (gender) to land on the moon was NeilArmstrong. .
b) If you are looking for a male "child" that landed on themoon, you are out of luck because not a single child has landed onthe moon as of 2014.

Rescuing the three astronauts of Apollo 13 was arguably the mostdifficult rescue mission in all of human history. It showed thathumankind is not willing to give up on those in need of help. For afew days, the whole world banded together in support of these threeindividuals -- even the USSR, whom the...

Saturn is a gas giant, and the first bit of solid ground is almost at the core, where the air pressure is too great. In the atmosphere, the winds (which are over 150 mph average) would tear most structures apart, and above the atmosphere wouldn't be ON saturn. You could always live on moons near...

The pressurized sphere made of aluminum alloy had five primaryscientific objectives: Test the method of placing an artificialsatellite into Earth orbit; provide information on the density ofthe atmosphere by calculating its lifetime in orbit; test radio andoptical methods of orbital tracking;...

The Space Shuttle Program was Commissioned by NASA and built by thejoint effoerts of United Space Alliance, Thiokol/ AlliantTechsystems, Lockheed Martin, and Boeing Rockwell. The SpaceShuttle program has nothing to do with religion and spirituality.

Constellations don't actually exist, (the stars in them exist, but... with very few exceptions ... the only connection between thestars in any given constellation is that they happen to be in moreor less the same direction from Earth, though they may be at vastlydifferent distances from Earth, so...

planets and galaxies though there are thdings such as meteorites and stars. e4ach star that we are able to see bhyere onj earth are suns on the other planhets. each planet has a different sun and some contain more than 1.

Ms. Ride was a paid astronaut selected by, and paid by, NASA. By today's standards, as a highly educated physicist in the space program, she would earn about $100,000 per year as an astronaut, but I cannot say what the income level was at the time of her service in the 1980's.

The biggest advantage to using robot probes is that you mostly don't care if the robots come back, or are destroyed. People, we care about. The biggest disadvantage to using robots is that they cannot fix themselves, and can only do the jobs that they are pre-programmed to do. They have no...

Weight is a function of gravity. As a person moves farther away from a source of gravity, such as the earth or moon, the amount of gravitational force they experience dwindles, until it is negligible. While weight is a local property, the person's mass is constant. In other words, while the person...

It is not the purpose of this site to write people's essays for them (and if it was, we would charge). However, allow me to suggest some advantages of space exploration, that you might want to write about: There are a lot of resources in space which we may be able to use on Earth; lots of sunlight...

Anyone can request observation time on HST - in the past, the Hubble Director has opened up his own time for use by amateur astronomers. Competition for time is fierce though, and is generally given to academics and scientists, though "targets of viewing opportunity" are considered if it falls...

With the developmentof the heliocentric model by Nicolaus Copernicus in the 16thcentury, the sun was believed to be the centre of the Universe,with the planets (including Earth) and stars orbiting it..

Well, for starters, they went in the lunar morning, when it hadn't warmed up yet. Remember, a lunar day is about 14 Earth days, so morning lasts a good long time! Second, there is no air on the Moon, so the only things that get hot are physical objects like the astronauts and the lunar soil. The...

Rainbows are caused by sunlight glinting off tiny water particles in the sky, bouncing the light back towards the observer. In other words, any time you see a rainbow directly in front of you, the Sun is directly behind you, and your shadow points at the center of the circle the rainbow is...
